Great. I'm now watching it. But can we also get a specific frequency sound from this set up please?

[@NizarMohideen]

You need passive buzzer for changing frequency as shown in czcams.com/video/zw1mQUI2sSM/video.html

[@NizarMohideen]

You can not change frequency for active buzzer. You need passive buzzer as shown in video no-21
